PORTELECTRIC.

SPECIFICATION forming part of Letters Patent No. 436,2S1, dated September 9, 1890.

Application tiled September 12, 1889. Serial No. 323,712. (No model.)

To all whom it may concern.:

Be it known that I, JOHN T. 'ILLIAMS, a citizen of the United States, residing at Mount Vernon, in the county ot "estehester and State of New York,have invented new and useful Improvements in Porteleetrics, of whichv the following is a specification.

This invention relates to portelcctrics; and it consists, among other things, of improvements whereby the electro magnet or magnets by means whereof the traveling car or carriage has motion imparted to it are mounted upon and travel with the car or carriage, the several improvements being hereinafter fully described, reference being had to the alecmpanyin g drawings, in which- Figure 1 is a central longitudinal section taken on the line a: of Fig. 9. Fig. 2 is a cross-section taken on the line y y of Fig. 1. Fig. 3 is an end view of the electro-magnet B, looking in the direction of the arrow placed on the magnet in Fig. 1. Fig. 4 is. a longitudinal section on t-he line t: v of Fig. 7,`showing two electro-magnets attached to the carriage. Fig. 5 is a cross-section taken on the line w w of Fig. 4. Fig. 6 is a cross-section of the electro-magnet B, taken on the line a: a'. of Fig. 4. Fig. 7 is a top view ot' the portelectric having two electro-magnets attached to the car or carriage. Fig. S is a central 1ongitudinal section of a modication, wherein the source of electricity, as well-as the elec tro-magnets, are carried on the carriage. Fig. 9 is a cross-section. taken on the line s z of Fig. 1, looking toward the electro-magnet B. Fig. 10 is a cross-section of one of the stationary cylinders or rings, A, through which the carriage travels, made in sections united to gether to form a ring or cylinder having slots therein to allow the air to escape through the same as the carriage approaches the ring. Fig. 11 is an elevation of a cylinder or ring whose sides are provided with slots to allow stationa ry cylinders or rings, of iron or other magnetizable metal, suitably supported, along with the guide-rails D D, upon a frame P, from which the rings are insulated by indiarubber or other suitable insulating material Q. A conductor of electricity E extends through the rings A and is insulated therefrom by the insulating-strip I.

The letter B designates an electromagnet, which is constructed and arranged in such a manner that it ctn pass into the ring A, the ends of its coil oi wire being attached to the contact-pieces C C'. (See Fig. 1.)

'lhe letter F designates the core of the electro-magnet, and designates the 'wire or the space occupied b v it. The core may consist of a number of iron. rires or may be in one piece.

'lhe electro-magnet B is surrounded by a covering of insulating material R, to which the contactpieces C C are connected, and its exterior is also provided with guides K K, adapted to slide in the rings A on either side of the conductor E to keep the electro-magnet in proper position in passing through the rings.

A battery or other source of electricity L having been provided, and the conductor E having been connected with one pole thereof by means of wire 2, and the ring A having been connect-ed with the otherpole of the battery through wire 1, as shown in Fig. 1, if now the electro-magnet B is moved iu the direction of the arrow thereon until the contactpiece C- comes in contact with the metal of ring A a circuit will be closed through wire 1, metal ring A, contact-piece C, wire G of electro-magnet B, contact-piece C', conductor E, and wire 2 to battery L. This will cause the cleetro-maguet B to be drawn into the cylinder or rin gil until their ends are in such relative positions that the contacts will be broken and the electro 'magnet will move on as far as its momentum will carry it. If new a series of such cylinders or rings A be arranged in succession at such intervals apart as lo allowafrcc escape of the air ahead ot' the electrfi-magnetA .1nd to allow the electron. .-t to be again vitalized through the mi rings before its momentum is exhausted, it- 'l; evident that a. continuous motion may be .imparted to the electro-magnet IOO through the whole series of cylinders or rings A, and ifa car or earriagebe provided adapted to move with the electro-magnet, a suitable track being provided on which the carriage and electro-magnet shall be properly guided, itis man ifestthattheir forward movement will continue until the last ring A in the series has been reached by the electro-magnet.

My present improvement consists in a portclcctric constructed and operated on this principle, and in Figs. 4 and 7 I have shown an arrangement wherein a portelectric car or carriage is constructed and adapted to continue a direct movement by the use of two such electro-magnets havin g a car or carriage attached to them.

Referring to Figs. 4- and 7, the letters A A A2 designate three such cylinders or rings of magnetizablc metal, and 1I designates a car or carriage adapted to move on the guiterails D D through said rings. The car or carriage ll is constructed of two electro-magnets B B-one at each end-and of an intermediate section of non-magnetic material H', the carriage being secured at its ends by screws V or other suitable fastenings to the cores F of the electro-magnets.

The rings A A' and the other similar rings iu the series are provided with brushes T T for making contact `with the contact pieces or strips C C', which are attached, respectively, to the inside and outside ends of the wires of the said electro-magnets. The brushes T '1" are fixed on supports S S', which are mounted ou the inner ends of the rings A A' A2 by means of insulated connections of india-rubber or other suitable insulating material lV. The electrical connections by this arrangementare as followsmamely: Wire l represents the wire from the positive pole of a ba 1to1-y or other source of electricity, and wire 2 the negative Wire. lVire l has a connection by wires 3 with each of the supports S for the series of brushes T, and wire 2 has similar connection by wires 3' u ith each of the supports S' for the series of brushes T' In the positions shown in Fig. 7 a current. would be established fromxvire l, through wire 3, brushsupport S, brush T, contact piece or strip C, wire of magnet B, contact piece or strip C', brush T', brush-support S', and wire 3', to wire 2. This current will draw the carriage 'll by the magnetic pull of magnet B into the ring A'. The current in magnet l; will be maintained while the brushes T T' of the ring A' remain in contact with the contact pieces or strips C C' of magnet B, and when this circuit is broken the magnet B' of the carriage will be #En position to perform the same operation with reference to the ring Ai', and when the action at the ring A2 ceases the magnet B will be in position to be acted on in the same manner in connection with, the ring A, and so on, the magnets B and l being,` so separated relative to the rings .its to assure ltheir alternate action continiwusly.

In 1-`ig. 8 I have shown a modi ication of this invention wherein the battery or source of electricity is carried in the car or carriage H and the alternate closing of the circuits ir. the electro-magnets of the carriage is accomplished by means of an oscillating lever M, which is pivoted at the middle of its length to the carriage on the pivot X, and whose forward end is provided with a projecting shoulder Y and its rear end with an upturned projection Z.

IVhen the carriage Il is in the position shown in Fig. 8, the end Y of lever M comes in contact with the cylinder or ring A,and is presseddownwardtherebyagainst thecontactpiece C on the magnet B, which is in electrical connection with the outer end of the coil of said magnet. This allows a current to pass through magnet B as follows,namely: from one pole of battery N, through wire 4, to lever M, contact-piece C, outer end of coil of magnet B, and through said coil and returnnire to the opposite pole of battery. This current will draw the carriage ll in the direction of the arrow at one end of Fig. 8 until the forward end Y of the lever passes through ring A,when it is released. At this moment, however, the other end Z of said lever strikes against the ring A' and is pressed downward against contact-piece C' of magnet B', said contact-piece 'C' being connected with the outer end of the coil of magnet B', and in consequence a current is established through magnet B' as follows, namely: from one pole of battery N, through wire 4, to lever M, through the said lever to i ts end Z, through contact-piece C' to the coil of magnet B', through said coil, and through Wire 5 to the battery. This current imparts an additional impulse to the carriage, and by providing a series of said iron cylinders or rings, as before explained, a similar continuous movement of the carriage through them will be obtained.

The cylinders or rings A can be made with longitudinal slots o to facilitate the escape of air from the rings when a carriage enters them, so that the carriage will not meet with much resistance of the air in passing through them. The slots o can be made in the rings after the rings are prepared, or the rings can be made of longitudinal sections 7 put together to form a ring in such a manner as to leave slots o between thc sections.

The carriage Il is provided with rrheels 8,

which may be placed at its ends for supporting and guiding it on the rails D D.

It is obvious that if a cylinder or ring having a longitudinal slot therein (see Fig. 10) extending through the cylinders or rings from end to end be used it would admit. of arms o. other projections being attached to the car or carriage that would pass freely through such slots of the cylinders or rings and serve to impart motion to a body or vehicle exterior of the apparatus itself to which the arms might he attached. Such a construction is shown in Fig. 12, where the carriage H is within a slotted cylinder or ring A, an arm 8,

which projects from the carriage, extending through the continuous slot o to a vehicle 9, arranged to travel on a parallel track 10 outside of the ring A, so that the carriage 1I, moving within the series of rings A, is enabled to communicate motion to a body or vehicle outside of said rings.

In the drawings the electrical connections between the rings A A A2, &c., and the electromagnets are arranged in such manner that they are operated as the electro-magnets enter or begin to enter the rings; but the oontactpieces C C' can, without departing from my invention, be arranged in such manner that contact will not be made with the rings un` til the electro-magnets have entered the rings a little distance-say half-way to the middle of the length of the rings, more or less,

What l claim as new, and desire to secu re by Letters Patent, is v 1.
